At ChinaJoy 2018 a new browser game based on Fate/stay night was revealed, and we got a sneak peek with an off-screen trailer taken from the booth at the expo. [Thanks, 4Gamer.]
According to the staff at the booth, the game will release in China sometime in the near future. No further information could be shared for the time being, but the game features turn-based battles with numerous Servants set to appear, and some PvP elements.
More information on the new browser game, including its title, will be revealed soon.
